To all whom it may concern: g

Be it known that I, HAVANAR V. Can- HANS, a citizen of the United States, resid ing at- Sherman, in the State ofTexas, have ,invented new and.usefulImprovementsf in e ol- Boll-Vteevil Destroyers, of which th lowing is a specification.

This invention contemplatesthe provision of a machine for killing boll weevils and other insects which destroy cotton plants and the like, and embodies amongst. other features, a plurality of brushes arranged to brush the plants and the ground about the latter, and to simultaneously saturate the same with a-solution which will destroy sa1d insects without any detrimental effect to the plants. v

'In carrying out the invention, I provide a novel construction of, means for operatin the brushes for the purpose specified, an for conveying the solution thereto from a supply tank forming :part of the. machine.

The nature and advantages of the invention'will bebetterunderstood when the following detailed description is read 1n connection with. the accompanying drawings, the invention residing in the constructlon, combination and arrangement of parts as "-In the'drawings forming part of this application, like. numerals of reference ind cate similar parts in the several views, and wherein v igure 1 is a side elevation. of the machine. I I

Figure 2 is a rear end elevation.

F igure 3 is a sectionalview taken on the line 3-3 of'Figurel- 1 I Figure 14 is atop plan vlew. t

Figure 5 is a longitudmalsectional view.

Referringto the drawings n detail, 10 indicates a wheeled frame,.which supports a 'li uid su ly tank. 14 arranged 'longitudinglly of iii; frame, and from which liquid is conveyed to the brushes to be hereinafter described. The tank 14 is provided with. a

fillingtube 12 normally closed by a cover of any suitable construction.

Arranged beneath the frame is aplurality 'ofbrushes adapted to be utilized forthe purpose herein above. stated, and these rushes are arranged in pairs indicatedat A; B and C respectively, The brushes of the pair A are arranged athacent the forward endot the machine, while the brushes a re.arranged in divergent relation at the" rear of'the machine, while the brushes C are arranged intermediate the machine adjacent the sides thereof and adapted to be moved toward each. other, so that the insects brushed from the plants onto the groundare subsequently brushed toward the center by the brushes C, where they can be saturated with the solution from the tank conveyed to the brushes B. The head of each brush A and B is form'ed to provide a compartment, and'communicates with a supply tube 13, which conveys the solution from the tank 14 to the respective brushes. These tubes 13 are of course flexible and are suitably coupled to the tank 14 by means of valve casings 15. A valve is arranged to operate in each valve casing so as to control the communication between the tank and the different'supply tubes leading to the various brushes, and these valvesare simultaneously operated by means ofa rod 16, which is reciprocated incident to the operation of the lever 17,. This lever is fulcrumed' as at 18 and is arranged within convenient reach of the operator of the machine, or in other words immediately atone sideof the seat 19. It-i of course to beunderstood that the solution is sprayed from the brushes under prespistonrod 22. The ingredients of liquid or solution is thorou hly mixed by means of an agitator 23whic is mounted upon a shaft 24 and rotated in a manner to be hereinafter described. The piston rod is reciprocated from the crank shaft which is rotated incident to the progression of the machine.

As will be noted from the drawings, the crankshaft 21 is provided with a small sprocket 25 over which anda large'r'sprocket 26 mounted'onthe axle supporting one of the traction" wheels is an endless chain 27.

Arranged adjacent the sprocket wheel 26, is

. a smaller sprocket wheel 28 over which and a larger sprocket wheel 29 is trained anendless chain 30. The shaft upon which the sprocket wheel 29 is mounted is provided with a crank portion 30' for a pur ore to be hereinafter described, and this S aft also supports asmaller sprocket wheel 31 over brushes G with which through the medium'of a taneously operated unison with the large sprocket wheel 34 meshing with a small sprocket wheel 35 carried by the shaft 24 of the agitator. So while the machine is moving over the ground, the various parts above described put into operation by simply engaging the clutch members 36 and: 37 respectively which are actuated in the usual manner through the instrumentality' of the clutch pedal 38.

Connected to the crankportions 30', and arranged at opposite sides of the machine, are rods 39 adapted to be reciprocated incident to the rotation of the crank portions 30', a and thus impart movement to the they are connected. The brushes are connected by branches 40 and 41 projecting from each rod 39 as clearly illustrated in Figure 1. These rods 39 are however associated with the crank portions ball and socket connections 42, allowing t e rods to be rotated toward and away from each other under the influence of the springs 43 connected with the rods 39 at up ropriate points in their lengths. The rods 39 turn thebearings 44 which are suprted by the ends of transverse rods 45, t e liftter having ball and socket connections 46 with a suitable support arranged beneath the .machine as clearly shown in Fi re 2. The upper end of each branch 41 o the respective rods 39 terminates to provide a loop or eye 47 which accommodate the adjacent end f a vertical rod 48, the upper end of which is connected as at 49 with a link 50 fulcrumed at 51 between the ends thereof. This link 5Q has its. 0 posite end vconnected with a link 52 whic is moved transverse bar 52 by an 0 rating lever 53 arranged at one side of the I ivers seat in convenient reach of the operator. Manifestly, by operating the lever 53, the link 50 is swung upon its fulcrum for the pur of raising or lowering the brushes toward or away from the ground asthe occasion may require. It .is of course to be understood that the brushes C at the opposite sides of the machine are simulincident to the movement of the lever 53.I .The construction of this part of the machine is such that the brushes are operated. in. the manner to brushthe insects, which have been previously brushed from the plants upon V e ground by the brushes A, intothe pathof movement of the brushes B which are arranged to follow the brushes 0 so that the insects'will be sprayed with the solution conveyed to the brushes B from the tank14. e

'Asabove stated, the insects are brushed brushed from t brushes 0, which are operated from the plants onto the ground by brushes A which are of course arranged adjacent the front of the machine and mounted to be swung in a vertical plane for this purpose in contra-distinction to the lateral or swinging movement of the brushes C. The brushes A are supported by rods. 54 which are held associated with t e flexible tubing 13 in any suitable manner, preferably by clamps 55. The rods 54 have correspondmg extremities connected with the crank portions 56 of shafts 57 as indicated at 58, and are also connected or sup rted by vertical rods 59 which depend rom the crank portions 60 of shaft 61. The shafts 57 and 61 are rotated in unisonin a manner to be presently described, and consequent? the rods 54 are iven a vertical movement or the purpose 0 brushing the plants with the rushes A and at the same time spra the pIlants with the solution from the tan 14. ow, the shaft 61 is rotated from the shaft 57 through the instrumentality of an endless chain 62 which is trained over a sprocket wheel 63 fixed upon the shaft 57 and over a larger sprocket wheel 64 carried by the shaft 61. The shaft 57 further supports a larger sprocket wheel 65 arranged to en age the adjacent run of the endless chain 2 so that the shaft is operated from this chain simultaneously wit the o ration of the piston within "the tank 14. he branches B are at the rear of the machine arranged in divergent relation and remain stationary being supported from a suitable bracket 66 shown in Figure 2. This bracket 66 is suitably connected with the flexible tubing or hose 13 which conveys the solution from the tank 14 to these brushes B. The brushes are suspended from the seat 19 by vertical rods 67 terminating in hooks 68 which receive and support the yoke 69 for this purpose.

In practice the machine is moved over the ground or surface in any suitable manner and during the progression of the machine the brushes A move in vertical planes to brush the plants, and at same time spray the latter'with the solution or li uid conveyed to the brushes from the tan 14. It is during this 0 eration that the insects are e plants onto the ground and these insects are'subsequently brushed toward the center of the machine by the in the manner above described, lateral] or at right angles to the brushes A. e insects are sub uently sprayed with the solution force from the tank 14 through the brushes B which also subsequently spray the plants as these brushes occupy positions approximately in planes between the brushes C for this purpose. These are thus arranged to swee the top of the plants.

While it is lieved that from the fore going description, the nature and advanthe i tages of the invention will be readil up parent, I desire to have it unders that do not limit myself to what is herein shown and described and that such chan s may be resorted to when desired as all within the scope of what is claimed.
